How to Install it on Ubuntu Linux -====== - -Recently, Oracle announced the general availability of Java 14 (or the Oracle JDK 14). If you are someone who wants to have the latest and greatest to experiment and develop stuff – you can try installing Java 14 on your Linux system. - -Oracle JDK 14 (or simply Java 14) [release][1] includes a couple of new features if you’re interested to preview them. I’ve linked them below: - - * [Pattern matching for instanceof][2] - * [Records][3] - * [Text Blocks][4] - - - -In addition to the preview features, it packs in several improvements and additions. Quoting the press release, they mentioned the additional improvements as well: - -> Additionally, the latest Java release adds Java language support for switch expressions, exposes new APIs for continuous monitoring of JDK Flight Recorder data, extends the availability of the low-latency Z Garbage Collector to macOS and Windows, and adds, in incubator modules, the packaging of self-contained Java applications and a new Foreign memory access API for safe, efficient access to memory outside of the Java heap. - -Of course, if you want to dive into the exact details, you should check the [official announcement][1]. - -In this tutorial, I’ll show you the easy way to get Java 14 installed on your Ubuntu system. Read on. - -**Note:** If you opt for Oracle Java 11 or above, you should learn about the new [Oracle Technology Network License Agreement][5] to know how it affects personal users, developers, and commercial organizations. Usually, these are free to use for development and testing – but not for production. - -### How To Install Java 14 on Ubuntu Linux? - -![][6] - -For reference, I’ve successfully tried it on **Pop!_OS 19.10** where I had the **OpenJDK 11** installed as the default. - -Here, we are going to use the Java 14 installer (originally based on WebUpd8 Java Package) by [Linux Uprising][7]. - -Simply enter the commands below in the terminal to get it installed: - -``` -sudo add-apt-repository ppa:linuxuprising/java -sudo apt update -sudo apt install oracle-java14-installer -``` - -This should do the job. And, when it’s done, if you want to make it the default, you can type in the following command to do it: - -``` -sudo apt install oracle-java14-set-default -``` - -It is worth noting that this is only for Ubuntu-based distributions. If you want to install it on Debian and other Linux distributions, you can follow [Linux Uprising’s detailed guide][7] on installing Java 14 as well. - -### Wrapping Up - -Of course, while this is about the bleeding edge features – if you do not want to break things, you might want to hold on to Java 11. If you want to experiment while knowing the risks, go ahead and give it a try! - -Feel free to let me know your thoughts on Java 14 in the comments below. - --------------------------------------------------------------------------------- - -via: https://itsfoss.com/java-14-ubuntu/ - -作者：[Ankush Das][a] -选题：[lujun9972][b] -译者：[译者ID](https://github.com/译者ID) -校对：[校对者ID](https://github.com/校对者ID) - -本文由 [LCTT](https://github.com/LCTT/TranslateProject) 原创编译，[Linux中国](https://linux.cn/) 荣誉推出 - -[a]: https://itsfoss.com/author/ankush/ -[b]: https://github.com/lujun9972 -[1]: https://www.oracle.com/corporate/pressrelease/oracle-announces-java14-031720.html -[2]: https://openjdk.java.net/jeps/305 -[3]: https://openjdk.java.net/jeps/359 -[4]: https://openjdk.java.net/jeps/368 -[5]: https://www.oracle.com/technetwork/java/javase/overview/oracle-jdk-faqs.html -[6]: https://i1.wp.com/itsfoss.com/wp-content/uploads/2020/03/install-java-14-ubuntu.png?ssl=1 -[7]: https://www.linuxuprising.com/2020/03/how-to-install-oracle-java-14-jdk14-on.html diff --git a/translated/tech/20200329 Oracle Announces Java 14- How to Install it on Ubuntu Linux.md b/translated/tech/20200329 Oracle Announces Java 14- How to Install it on Ubuntu Linux.md new file mode 100644 index 0000000000..e030ed192e --- /dev/null +++ b/translated/tech/20200329 Oracle Announces Java 14- How to Install it on Ubuntu Linux.md @@ -0,0 +1,82 @@ +[#]: collector: (lujun9972) +[#]: translator: (geekpi) +[#]: reviewer: ( ) +[#]: publisher: ( ) +[#]: url: ( ) +[#]: subject: (Oracle Announces Java 14!
